Supply H142X stainless steel hydraulic level control valve full copper H142X hydraulic level control valve students ..

Second, the Shanghai High-wide copper bolt hydraulic level control valve Products H142X hydraulic level control valve, is an automatic control of water tanks, water tower liquid level of the hydraulic control valve. When the water dropped by more than a preset value, the float valve opens, the piston chamber pressure is reduced, the piston down the formation pressure in this pressure differential valve opens the water supply operation; when the water level rises to a preset height, the float valve closed, the piston chamber pressure is increasing causing the valve closed to stop water supply. This back and forth at a set height automatic level control, automatic water supply function. Third, the Shanghai High-wide copper bolt hydraulic level control valve scope of application of the hydraulic level control valve is fixed into the vertical pipe, then the control tube, float valve shut-off valve and tighten the connection to the valve. Hydraulic level control valve inlet and outlet pipe connection flange H142X-4T-A is 0.6MPa standard flange; H142X-10-A to 1MPa standard flanges. The inlet valve diameter should be greater than or equal to the nominal diameter, the outlet should be less than the float valve. Float valve should be installed at least one meter away from the water; in the tank outlet pipe above the water line at the drill a small hole to prevent air straight backwater. When used, the cut-off valve should be open, like a pool installed just above two valves should be maintained at the same level. Because the main valve closed lag float valve closed about 30 to 50 seconds, so the tanks have enough spare volume to prevent overflow. To prevent impurities, sand into the valve failure caused by work, the valve should be installed before the filter. As installed in the underground tank, you should install an alarm system in the underground pumping station. Fourth, the Shanghai High-wide copper bolt hydraulic level control valve structure characteristics 1, the use of hydraulic principles control, the new structure is reasonable. 2, smooth and reliable. Within a predetermined pressure range, can ensure water hammer impact. 3, hydraulic level control valve light weight, small size. 4, easy installation and maintenance. Fifth, the Shanghai high overall copper bolt hydraulic level control valve works: When the water level inside the tank or water tower fell, the float valve to open the drain when there is pressure in the inlet water will hold up in the valve piston sealing surface to open the valve that is open water, When the water level rises to the control valve, the float valve is closed, the sealing surface of the piston down closed hydraulic valve stops water level control valve, main dimensions and weight DN 40 50 65 80 100 125 150 200 250 300 350 L 107 115 125 135 146 165 180 215 255 285 325 H 235 243 258 280 307 358 400 490 576 663 750 note: the above dimensions for reference only, subject to change without notice.
